BACKGROUND

In the water channel system of smart bathroom equipment, a water channel distributor is usually set to control the water channels so that the water outlet mode can meet the needs of users.

The water channel distributor usually uses a stator and a rotor to cooperate to realize the water channel control. Specifically, the stator is provided with a plurality of water inlets along the circumferential direction, and the rotor is provided with a water outlet, and the water outlet and the water inlets are on the same circumference. The rotor and the stator are relatively rotated. When the water outlet on the rotor coincides with one of the water inlets on the stator, one water channel is opened and other water channels are closed to realize the switching of different water channels. In the actual operation process, the applicant found that the above-mentioned electromagnetic distributor has the following shortcomings: firstly, the distributor uses a stepper motor to control the rotor to rotate in the circumferential direction to control the position of the water outlet to realize the switching of different water channels. The response time is relatively long and cannot meet the needs of rapid switching; secondly, the opening and closing of each water channel of the distributor cannot be independently controlled and only one water channel can be opened at the same time. The water outlet method is single, which cannot meet the diverse water outlet needs.

Therefore, these or other directional terms should not be interpreted as restrictive terms.

As shown in FIGS. 1 to 4, the electromagnetic distributor provided by the present disclosure comprises: a housing 1, at least two solenoid valve cores 2, and a magnetic conducting part 3.

Please refer to FIGS. 1 to 4 at the same time, the housing 1 is provided with a water inlet 10 and at least two water outlets 11 connected with the water inlet 10. The at least two solenoid valve cores 2 and the at least two water outlets 11 are arranged in one-to-one correspondence. At least two magnetic conducting chambers 30 are arranged on the magnetic conducting part 3, an electromagnetic loop is formed in any one of the magnetic conducting chambers 30. The at least two solenoid valve cores 2 are arranged in one-to-one correspondence in the at least two magnetic conducting chambers 30. Any one of the solenoid valve cores 2 moves away from or close to the corresponding water outlet 11 under the action of the magnetic field generated by the corresponding electromagnetic loop, so as to independently control the opening and closing of the corresponding water outlet 11.

It should be noted that the magnetic field force generated by the electromagnetic loop is a vector force. By switching the direction of current on the electromagnetic loop, a magnetic field force directed to the corresponding water outlet 11 or a magnetic field force directed away from the corresponding water outlet 11 can be generated on the solenoid valve core 2. When the solenoid valve core 2 receives the magnetic field force directed to the corresponding water outlet 11, the solenoid valve core 2 moves toward the corresponding water outlet 11 until it abuts on the corresponding water outlet 11, so that the corresponding water outlet 11 is in a closed state. When the solenoid valve core 2 receives a magnetic field force directed away from the corresponding water outlet 11, the solenoid valve core 2 moves away from the corresponding water outlet 11 until it separates from the corresponding water outlet 11, so that the corresponding water outlet 11 is in an open state. The solenoid valve core 2 in this embodiment may be a stainless soft magnetic valve core, which has good magnetism and corrosion resistance.

FIGS. 2 and 3 show that the number of the solenoid valve cores 2 is four, and the four solenoid valve cores 2 are arranged in one-to-one correspondence with the four water outlets 11. Each solenoid valve core 2 can individually control the opening and closing of the corresponding water outlet 11. By arbitrarily combining the control states of the four solenoid valve cores 2, a variety of water outlet modes can be realized. For example, among the four solenoid valve cores 2, two solenoid valve cores 2 all control the corresponding water outlets 11 to close, and the other two solenoid valve cores 2 alternately control the corresponding water outlets 11 to open. Optionally, any water outlet 11 can be connected to the water inlet of the spray nozzle and the outlet of the spray nozzle is used to clean the human body. When at least two water outlets 11 have multiple water outlet modes, there are also multiple water outlet types of the water outlets of the corresponding spray nozzle. The number of solenoid valve cores 2 is not limited to four and the control combination mode between the solenoid valve cores 2 is also not limited to the above-described modes.

The electromagnetic distributor provided by the embodiments of the present disclosure controls at least two water outlets 11 in a one-to-one correspondence through at least two solenoid valve cores 2. Each solenoid valve core 2 can independently move closer to or away from the corresponding water outlet 11 under the force generated by a corresponding magnetic field in order to independently control the opening and closing of the corresponding water outlet 11 and achieve the effect of independent opening and closing of the at least two water outlets 11. By individually controlling the direction of the magnetic field force in each magnetic conducting chamber 30, the arbitrary switching and combination of the opening and closing states of the at least two water outlets 11 can be realized and a variety of water outlet methods can be achieved. After the magnetic field force in the magnetic conducting chamber 30 is generated, the solenoid valve core 2 is immediately forced to move, which accelerates the response speed and shortens the response time.

In one embodiment, the electromagnetic distributor further comprises at least two permanent magnets 34 and the at least two permanent magnets 34 are arranged in the at least two magnetic conducting chambers 30 in one-to-one correspondence. Any one of the solenoid valve cores 2 is located between the corresponding permanent magnet 34 and the water outlet 11. When the magnetic field force disappears or it faces away from the corresponding water outlet 11, the solenoid valve core 2 can be adsorbed on the permanent magnet 34 and kept away from the corresponding water outlet 11, preventing the solenoid valve core 2 from being closed by mistake due to shaking and other causes and increasing the control accuracy. When the magnetic field force directs to the corresponding water outlet 11 and the magnetic field force received by the solenoid valve core 2 is greater than the adsorption force of the permanent magnet 34 on the solenoid valve core 2, the solenoid valve core 2 separates from the permanent magnet 34 and moves toward the direction close to the corresponding water outlet 11. The permanent magnet 34 in this embodiment may be a neodymium iron boron magnet to have better magnetism.

In one embodiment, the electromagnetic distributor further comprises a sealing gasket 37, the sealing gasket 37 is sealingly arranged in the magnetic conducting chamber 30 and located between the permanent magnet 34 and the solenoid valve core 2. The sealing gasket 37 in this embodiment can reduce the impact noise generated by the solenoid valve core 2 hitting the permanent magnet 34 and the impact on the permanent magnet 34 when the solenoid valve core 2 reciprocates between the permanent magnet 34 and the water outlet 11, thereby buffering and reducing noise effect. In addition, the sealing gasket 37 in this embodiment also functions to seal and isolate the permanent magnet 34 and the solenoid valve core 2, preventing the water entering the housing 1 from the water inlet 10 from immersing under the permanent magnet 34, thereby improving the sealing effect. FIGS. 2 and 3 show an alternative structure of the sealing gasket 37. As shown in FIGS. 2 and 3, the sealing gasket 37 can be a sleeve structure with one end closed, and the closed end of the sleeve structure is located between the solenoid valve core 2 and the permanent magnets 34, which has the effect of buffering and reducing noise. The part of the sleeve structure extending in the axial direction is used to accommodate the solenoid valve core 2 and guide the solenoid valve core 2 when the solenoid valve core 2 reciprocates. The sealing gasket 37 in this embodiment may be an Ethylene-Propylene-Diene Monomer (EPDM) rubber sealing gasket which has good corrosion resistance and aging resistance effects.

In one embodiment, the electromagnetic distributor further comprises an elastic part 36, the elastic part 36 is compressed and arranged between the solenoid valve core 2 and the sealing gasket 37. The elastic part 36 in this embodiment is always in a compressed state during the reciprocating movement of the solenoid valve core 2, so as to provide a stable supporting force to the solenoid valve core 2 when the solenoid valve core 2 moves to abut on the corresponding water outlet 11 to enable the solenoid valve core 2 to stably block the water outlet 11. FIGS. 2 and 3 show an alternative structure of the elastic part 36. As shown in FIGS. 2 and 3, the elastic part 36 may be a spring and the solenoid valve core 2 is provided with a mounting hole at the end facing the sealing gasket 37 for accommodating the spring. The axial direction of the mounting hole is consistent with the movement direction of the solenoid valve core 2 and the axial direction of the solenoid valve core 2, so as to guide the spring in the axial direction of the solenoid valve core 2 so that the elastic force of the spring is always kept consistent with the axial direction of the solenoid valve core 2. The spring can be made of SUS316 stainless steel to have good corrosion resistance and toughness.

In one embodiment, the electromagnetic distributor further comprises a sealing cap 4 with elasticity, the sealing cap 4 is arranged on the solenoid valve core 2 and disposed at an outer side of an end of the solenoid valve core 2 close to the corresponding water outlet 11, so as to seal the water outlet 11 when the solenoid valve core 2 abuts on the corresponding water outlet 11. The sealing cap 4 in this embodiment can undergo a certain deformation after being squeezed by the solenoid valve core 2 and tightly abut on the corresponding water outlet 11 to improve the sealing effect of the water outlet 11. FIGS. 2 and 3 show an optional structure of the sealing cap 4. As shown in FIGS. 2 and 3, the sealing cap 4 can be provided with a necking embedding groove. One end of the solenoid valve core 2 facing the corresponding water outlet 11 is provided with a clamping boss and a diameter reduction part with its outer diameter smaller than the clamping boss. The clamping boss is clamped into the embedding groove and is confined in the embedding groove by the necking opening. The diameter reduction part is clamped at the necking opening of the embedding groove, which increases the stability of the structure of the sealing cap 4 being installed on the solenoid valve core 2. The sealing cap 4 in this embodiment may be an EPDM (Ethylene-Propylene-Diene Monomer) rubber cap to have good corrosion resistance and aging resistance effects.

In one embodiment, the magnetic conducting part 3 comprises a magnetic conducting upper cover 31 and a magnetic conducting lower cover 32. The magnetic conducting upper cover 31 and the magnetic conducting lower cover 32 are interlocked to define an accommodating chamber and at least two coil frames 33 are arranged in the accommodating chamber. Any one of the coil frames 33 is wound with an electromagnetic coil and any one of the coil frames 33 is provided with the magnetic conducting chamber 30. Both the magnetic conducting upper cover 31 and the magnetic conducting lower cover 32 in this embodiment can be made of magnetic materials such as pure iron and can be connected by riveting to form an electromagnetic loop. The electromagnetic coil may be a copper coil, and the electromagnetic coil forms a magnetic field extending in the axial direction of the solenoid valve core 2 in the magnetic conducting chamber 30 after being powered on. When the direction of the current changes, the direction of the magnetic field also changes. For example, when a forward voltage (e.g., 24V) is provided to the electromagnetic coil, the electromagnetic coil generates a magnetic field force on the solenoid valve core 2 directed to the water outlet 11. The solenoid valve core 2 may overcome the attractive force of the permanent magnet 34 under the action of the magnetic field force to move toward the direction close to the corresponding water outlet 11 until it abuts on the corresponding water outlet 11. The solenoid valve core 2 may keep the static state of abutting on the corresponding water outlet 11 under the action of the elastic part 36, thereby blocking the corresponding water outlet 11 to control the corresponding water outlet 11 to close. When a reverse voltage is provided to the electromagnetic coil, the electromagnetic coil generates a magnetic field force on the solenoid valve core 2 directed away from the water outlet 11. The solenoid valve core 2 may move downward against the elastic force of the elastic part 36 under the action of the magnetic field force until it abuts on the sealing gasket 37. The solenoid valve core 2 may keep a static state under the attraction of the permanent magnet 34, so that the corresponding water outlet 11 is opened and water outflow is restored. In addition, when pulse power is applied to the electromagnetic coil, the solenoid valve core 2 reciprocates with the pulse frequency and controls the water outlet 11 to open and close at the pulse frequency so that the corresponding water outlet 11 discharges water at the pulse frequency. Once the pulse frequency changes, the frequency of the water outflow of the corresponding water outlet 11 will be changed accordingly to meet various user's needs. As shown in FIG. 2, four coil frames 33 can be arranged in sequence to reduce the interference of their respective magnetic fields.

In one embodiment, the electromagnetic distributor further comprises a magnetic conducting rod 35, the magnetic conducting rod 35 is arranged in the magnetic conducting chamber 30 and located at the side of the permanent magnet 34 facing away from the solenoid valve core 2. The magnetic conducting rod 35 in this embodiment can guide the magnetic field force generated by the electromagnetic coil to the direction consistent with the axial direction of the solenoid valve core 2 to enhance the magnetic field force acting on the solenoid valve core 2. The magnetic conducting rod 35 in this embodiment can be made of a magnetic conducting material such as pure iron, which is easy to magnetize.

In one embodiment, the housing 1 includes a valve upper cover 12, a valve middle cover 13, and a valve lower cover 14 that are sequentially connected. The water inlet 10 and the at least two water outlets 11 are both arranged on the valve upper cover 12. The valve middle cover 13 is provided with at least two guide holes. The magnetic conducting part 3 is located between the valve middle cover 13 and the valve lower cover 14. The at least two solenoid valve cores 2 pass through the at least two guide holes in one-to-one correspondence and then extend toward the corresponding water outlets 11. The valve upper cover 12, the valve middle cover 13 and the valve lower cover 14 in this embodiment are connected to form a closed housing 1 structure, wherein the guide hole plays a role of guiding the solenoid valve core 2. The valve upper cover 12 and the valve middle cover 13 can be connected by ultrasonic welding to define a chamber through which water can flow in and out as shown in FIG. 2. The valve middle cover 13 and the valve lower cover 14 can also be connected by ultrasonic welding to define a chamber for installing the magnetic conducting part 3 and the solenoid valve core 2. After the valve middle cover 13 and the valve lower cover 14 are welded and connected, by size defining, the magnetic conducting upper cover 31 and the magnetic conducting lower cover 32 located between the valve middle cover 13 and the valve lower cover 14 and connected each other by riveting can be tightened and restricted. FIG. 2 shows an alternative embodiment in which the solenoid valve core 2 passes through the guide hole. It can be seen from the FIG. 2 that the sealing cap 4 sleeved on the end of the solenoid valve core 2 and the solenoid valve core 2 are both embedded in the guide hole, the friction between the solenoid valve core 2 and the inner wall of the guide hole can be reduced, and the solenoid valve core 2 can be protected.

In one embodiment, the electromagnetic distributor further comprises a threading plug 5. A threading hole is provided on the valve lower cover 14 and the threading plug 5 is clamped on the threading hole. Both ends of the electromagnetic coil pass through the housing 1 from the threading plug 5. The threading plug 5 in this embodiment facilitates the two ends of the electromagnetic coil to pass through the housing 1 to be installed on the power supply terminals and the power supply to the electromagnetic coil is realized through the power supply terminals. The threading plug 5 in this embodiment can be a rubber plug. The rubber plug produces a tightening and sealing effect on the part of the electromagnetic coil that passes through the rubber plug under the action of its own elasticity, which enhances the structural stability of the part of the electromagnetic coil that passes through the threading plug 5. As shown in FIGS. 2 and 3, when the number of the coil frames 33 is four, both ends of the electromagnetic coil wound on each coil frame 33 all penetrate out of the housing 1 through the rubber plug. The rubber plug is used to position the parts of which each electromagnetic coil penetrates out of the housing 1, which is beneficial to avoid signal interference between the electromagnetic coils and further improve the accuracy of control.

By individually controlling the direction of the magnetic field force in each magnetic conducting chamber 30, the arbitrary switching and combination of the opening and closing states of the at least two water outlets 11 can be realized and a variety of water outlet methods can be achieved. After the magnetic field force in the magnetic conducting chamber 30 is generated, the solenoid valve core 2 is immediately forced to move, which accelerates the response speed and shortens the response time.

As shown in FIG. 5, the present disclosure further provides a method for opening and closing each water outlet 11 of the electromagnetic distributor as discussed above. A user may send a request to the controller as discussed above to open or close the water outlets 11. The request may be a request to open or close a particular water outlet 11. When receiving the request from the user, the controller may initiate the method of the present disclosure by sending an instruction to the sensor as discussed above.

At S101, when receiving the instruction from the controller, the sensor may detect a current position, relative to each water outlet 11, of the solenoid valve core 2 in the corresponding magnetic conducting chamber 30. Specifically, the sensor may detect whether the solenoid valve core 2 abuts on the corresponding water outlet 11 or the corresponding sealing gasket 37. The sensor may detect whether the solenoid valve core 2 is disposed at a position between the corresponding water outlet 11 and the corresponding sealing gasket 37. In an embodiment, only one sensor may be included to detect the current position of each of the solenoid valve cores 2. In another embodiment, the number of the sensors may correspond to the number of the solenoid valve cores 2. Thus, each of the sensors may respectively detect the current position of the corresponding solenoid valve core 2. In an embodiment, the sensor may selectively detect the current position of a particular solenoid valve core 2 according to the instruction from the controller.

At S102, the controller may determine a current state of the water outlet 11 according to the detected current position of the corresponding solenoid valve core 2. The current state of the water outlet 11 may be an open state or a closed state. Specifically, the controller may determine that the water outlet 11 is in the open state when the corresponding solenoid valve core 2 abuts on the corresponding sealing gasket 37. The controller may also determine that the water outlet 11 is in the open state when the corresponding solenoid valve core 2 is disposed at any position between the corresponding water outlet 11 and the corresponding sealing gasket 37. The controller may determine that the water outlet 11 is in the close state when the corresponding solenoid valve core 2 abuts on the corresponding water outlet 11.

The acts S103-S111 below illustrate how the controller adjusts a direction and an amount of the magnetic field force on the solenoid valve cores 2 according to the determined current state of each water outlet 11. The acts S103-S111 below further illustrate how the controller controls a movement, relative to the at least one water outlet 11, of each solenoid valve core 2 according to the adjusted direction and the adjusted amount of the magnetic field force on each solenoid valve core 2.

At S103, when the controller determines that the water outlet 11 is in the open state, the controller may further determine whether a magnetic field force in the magnetic conducting chamber 30 is directed to the corresponding water outlet 11. As discussed above, the electromagnetic coil may generate a magnetic field force on the solenoid valve core 2 in the magnetic conducting chamber 30. When a forward voltage (e.g., 24V) is provided to the electromagnetic coil, the electromagnetic coil generates a magnetic field force on the solenoid valve core 2 directed to the water outlet 11.

At S104, when the controller determines that the magnetic field force in the magnetic conducting chamber 30 is directed to the corresponding water outlet 11, the controller may further determine whether the magnetic field force in the magnetic conducting chamber 30 is larger than an attraction of the corresponding permanent magnet 34. As discussed above, the permanent magnet 34 may generate an attraction, directed away from the water outlet 11, on the solenoid valve core 2.

When the controller determines that the magnetic field force in the magnetic conducting chamber 30 is not directed to the corresponding water outlet 11, the corresponding water outlet 11 is maintained in its current state (i.e. the open state) at S111.

In another embodiment, when the controller determines that the magnetic field force in the magnetic conducting chamber 30 is not directed to the corresponding water outlet 11 and receives a request to close the water outlet 11 from the user, the controller may adjust the magnetic field force to direct toward the water outlet 11 by providing the forward voltage to the electromagnetic coil. Thus, the method proceeds to S105 instead of S111.

At S105, when the controller determines that the magnetic field force in the magnetic conducting chamber 30 is larger than the attraction of the corresponding permanent magnet 34, the magnetic field force may move the solenoid valve core 2 toward the corresponding water outlet 11.

When the controller determines that the magnetic field force in the magnetic conducting chamber 30 is not larger than the attraction of the corresponding permanent magnet 34, the corresponding water outlet 11 is maintained in its current state (i.e. the open state) at S111.

In another embodiment, when the controller determines that the magnetic field force in the magnetic conducting chamber 30 is not larger than the attraction of the corresponding permanent magnet 34 and receives a request to close the water outlet 11 from the user, the controller may adjust the magnetic field force to be larger than the attraction of the corresponding permanent magnet 34. Thus, the method proceeds to S106 instead of S111.

At S106, under the magnetic field force, the solenoid valve core 2 is moved toward the corresponding water outlet 11 until the solenoid valve core 2 abuts on the corresponding water outlet 11. Thus, the corresponding water outlet 11 is closed and maintained in the closed state.

At S107, when the controller determines that the water outlet 11 is in the closed state, the controller may further determine whether a magnetic field force in the magnetic conducting chamber 30 is directed away from the corresponding water outlet 11. As discussed above, when a reverse voltage is provided to the electromagnetic coil, the electromagnetic coil generates a magnetic field force on the solenoid valve core 2 directed away from the water outlet 11.

At S108, when the controller determines that the magnetic field force in the magnetic conducting chamber 30 is directed away from the corresponding water outlet 11, the controller may further determine whether the magnetic field force in the magnetic conducting chamber 30 is larger than an elastic force of the corresponding elastic part 36. As discussed above, the elastic part 36 may generate an elastic force, directed toward the water outlet 11, on the solenoid valve core 2.

When the controller determines that the magnetic field force in the magnetic conducting chamber 30 is not directed away from the corresponding water outlet 11, the corresponding water outlet 11 is maintained in its current state (i.e. the closed state) at S111.

In another embodiment, when the controller determines that the magnetic field force in the magnetic conducting chamber 30 is not directed away from the corresponding water outlet 11 and receives a request to open the water outlet 11 from the user, the controller may adjust the magnetic field force to direct away from the water outlet 11 by providing the reverse voltage to the electromagnetic coil. Thus, the method proceeds to S109 instead of S111.

At S109, when the controller determines that the magnetic field force in the magnetic conducting chamber 30 is larger than the elastic force of the corresponding elastic part 36, the magnetic field force may move the solenoid valve core 2 away from the corresponding water outlet 11.

When the controller determines that the magnetic field force in the magnetic conducting chamber 30 is not larger than the elastic force of the corresponding elastic part 36, the corresponding water outlet 11 is maintained in its current state (i.e. the closed state) at S111.

In another embodiment, when the controller determines that the magnetic field force in the magnetic conducting chamber 30 is not larger than the elastic force of the corresponding elastic part 36 and receives a request to open the water outlet 11 from the user, the controller may adjust the magnetic field force to be larger than the elastic force of the corresponding elastic part 36. Thus, the method proceeds to S110 instead of S111.

At S110, under the magnetic field force, the solenoid valve core 2 is moved away from the corresponding water outlet 11 until the solenoid valve core 2 abuts on the corresponding sealing gasket 37. Thus, the corresponding water outlet 11 is open and maintained in the open state.

The method according to the present disclosure controls at least one water outlet 11 according to the request from the user. For example, at least two water outlets 11 may be controlled through the corresponding solenoid valve cores 2. Each solenoid valve core 2 can independently move closer to or away from the corresponding water outlet 11 under the force generated by a corresponding magnetic field in order to independently control the opening and closing of the corresponding water outlet 11 and achieve the effect of independent opening and closing of the at least two water outlets 11. By individually controlling the direction of the magnetic field force in each magnetic conducting chamber 30, the arbitrary switching and combination of the opening and closing states of the at least two water outlets 11 can be realized and a variety of water outlet methods can be achieved. After the magnetic field force in the magnetic conducting chamber 30 is generated, the solenoid valve core 2 is immediately forced to move, which accelerates the response speed and shortens the response time.

Although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: the technical solutions recorded in the foregoing embodiments can be modified, or some of the technical features can be equivalently replaced.
